Fig. 11 is a sectional view taken on lines 1111 of Fig.9, and i i Fig. 12 is a detail View showing the in operative position'of the control lugshown" in Fig.11. v I a The present invention is. particularly adapted for use in connection with a motor truck. and includes movable, receptaclef mounted upon a track carried by the truck and movable by cables operated by the truck. engine to be raised from -'a lower rear receiv-. ing positionto. the upper central discharge position. The invention" also includes specific structural arrangements whereby the device provides novel improved structure, and the invention also includes suitable transmission means for controlling the actuation of the receptacle moving cables. '1

Referring more particularly to Fig. 1, the truck as indicated. includes a frame 10, upon which the truckbodyll which is adapted to receive the material is mounted, -The-mov-- able receptacle is indicated by, the numeral 12. and is provided with extending lugs 13 which extend outwardly and inwardly from the side of the receptacle, as shown in Figs. 1V and 10, the'extremities of the lugs being provided: with a pair of spaced rollersv 14,.which "move upon a track 15, which is substantially U-" shaped in cross section,'the' arrangement beingsrich'thatjthe outer roller 14 is carried between the sides of the U. while the inner roller moves on the outer face of the outer leg of the U. 1 It" will be seen thatthis arrangement provides for vmaintainingv the re ceptacle "in conjunction with the'track' and provides proper roller bearing between the receptacle and the track regardless of the movement of the receptacle over the track.

For moving the receptacle 12, a pair of cables 16 are provided, one end of each of which is secured to the top of the receptacle adjacent the receiving door. 18, while the opposite end is secured tothe receptacle adj acent the discharge door 19 and adjacent the lower lug 13, as indicated at 20. The'cable passes from the attachment point 17 over pulleys 21 which are preferably carried by the track, as illustrated in detail in Fig. 7. From the pulleys 21, the cable passes to the controlling pulleys 22 which may be operated by the truck engine as will be hereinafter described. The lower portion of the cables extends therefrom over the lowermost pulley 21 to be attached to the receptacle as at 20.

Referring more particularly to Fig. 8, it will be seen that the receptacle includes a receiving door 18, which is hinge-dly mounted u on a cross bar 23 of the receptacle and w an the face t'acle is in receiving position, as shown in Fig. 1, the door lies in a parallel plane when in closed position and may be hing'edly moved to a vertical open position to admit material to the receptacle. It will be understood that the receiving door 18 may be secured in closed positionby any suitable latch structure, such as is diagrammatically illustrated at 24 in Fig. 3. The receptacle also includes the discharge door 19 which when the receptacle is in receiving position lies vertical and forms the back of the re-' 'ce tacle, but when the receptacle is in the raised dischargin position shown in Fig.8, the discharging oor 19 is in parallel position when closed and may be dropped down to the vertical position shown in Fig. 8, as will be hereinafter described.

For moving the receptacle it will be understood that the cables 16 are adapted to be wound about the pulleys 22, whereby rot-ation of the pulleys causes the cables to move the receptacle upon the track 15. By referring more particularly to Figs. 4, 5 and 6, it will be seen that the pulleys 22 are mounted upon a transversely-extending shaft 25 which passes through a. transmission housing 26, the shaft 25 being provided Within the housin? 26 with a worm gear 27 mounted for ro-.

ta ion therewith. In mesh with the gear 27, a -gear 28 is provided, associated with which a smpller gear 29 is provided. i

or driving the cables .16 in a direction to lift the receptacle 12 from the receiving position shown m Fig. 3 a driven. shaft 30 asso-l ciated with the engine is provided, which ea tends within the housing 26. The shaft 30 is provided. with a gear 31 mounted thereon and a. sleeve '32 upon which a gear33 is mounted and which terminates in a slo ing. projecting.

flange 34, th'e' arrangement being such 'that the sleeve is movsbe longitudinally of the shaft 30 to which it is keyed, by a suitable key 35. The sleeve 32 is normally held in the position shown in Figs. 5 and 6, by an expansion spring 37, and it may be moved forwardly by a yoke 38 carried by a shaft 39 and be longitudinally movable forwardly by the rearward movement of a control lever 40, as shown in Figs. 1 and 3. In. the rearward neutral position shown in Fig. 6, it will be seen, by referring to Fig. 5, that the gear v33 is not in mesh with the intermediate gear rection, the shaft 42 is provided within the.

housing 26, upon which a sleeve 43 is keyed, the sleeve 43 being retained in the neutral position shown in Fig. 6 by a contraction spring 44. The shaft 43 has mounted thereon a gear 45, and the sleeve may bemoved rearwardly by a yoke 46 carried by the ex tremity of the shaft 39. Thus u on forward movement of the lever 40, the s eeve 43 will be moved rearwardly carrying wit it the gear and a gear 47 which is also mounted upon the sleeve 43. This movement of the gear 45 will move it into mesh with the gear 41, whereby the sleeve 43 will be rotated, and at the same time, the gear 47 will be brought to enmeshment with the intermediate gear 41 and will rotate it in the opposite direction to the rotation imparted t iereto bythe gear 43, whereby the receptacle maybe moved in an opposite direction along the track and will be returned from'the discharging posi tion shown in Fig. 8 to the loading position shown in Figs. 1, 2 and 7.. r

For locking the sleeves 32 and 43 in their adjusted position as movedby the forward or rearward movement of the lever 40, the end of each sleeve is provided with a tapering projection. as shown at 340m the sleeve 32 and at 48 on the sleeve 43.

By referring to Fig. 5, it will be seen that adjacent each sleeve, 1 spring-pressed, 1mger 49 is provided, w ich is mounte upon the extremity of a lever 50. which is pivoted to the casing as at '51, the arrangement being such that forward movement of the sleeve 32 or rearward movement of the sleeve 43 will cam out its respective plunger 48 against the,

action of the plunger spring and willpermit the plunger to be forced by its ownspring against the fiat rear side of the, proiection, thus holding the gears and sleeves in their adjusted position. I The arrangement will be seento be such that a single forward or rearward movement of the lever 40 will s t the gears and the plungers 4:9 will retain the gears in set position until the required move- I .ment of the receptacle has been completed.

, movable within guiding vstraps 56. The rear end of the link 55 is provided with a pivot ally mounted dog 57, which is adapted to be engaged by a catch 58 carried by the side of the receptacle 12, whereby when the receptacle has reached the position shown in Fig. 8, the catch. 58 will engage the dog 57 and longitudinally move the link 55. The forward end of the link 55 terminates in an inwardly extending angular portion 59 which cooperates with a crank 60 to rock a transversely extending shaft 61 which extends to to the center of the vehicle. At the center I of the vehicle the shaft 61 is provided with alink 63 and raise the plunger 49 to release the sleeve 32, allowing it to move under the influence of its spring-.37, to the neutral position shown in Fig. 6. V

For releasing the sleeve 43 when the receptacle is in the receiving position shown in Fig. 1, the catch 58 of the receptacleis adapt ed to strike the free arm of a bell crank, thus moving forwardly a connecting link 66 shown in Fig. 1,.which rocks a connecting bell crank 67 which is associated with the lever 50 associated with the sleeve 43. Thus the plunger associated withthat sleeve is moved upwardly against the tension of its spring and the sleeve is released to be moved by the spring 44; to the neutral position shown in Fig. 6. It will readily be seen that the arrangement is such that the attendant need only to set the gears by movement of the lever LOto raise or lower the receptacle 12 and that at the end of the desired movement of the receptacle the linkage connections will be such as to release the gears, allowing them to assume the normal neutral position shown.

As shown in Figs. 11 and 12, the dog 57 i is pivotally associated with the link in such a manner that it may be moved to the position shown in Fig. 12, whereby the recep tacle may pass thereover and be stopped by a similar dog arranged farther forward on the link 55. Thus a selection in the position at which the receptacle is brought to rest maybe readily attained.

For automatically opening the discharge a door 19 of the receptacle, the dog 57 is pro-' vided With an inwardly extending angled extremity 68, as shown in Figs. 9 and 10.

The receptaclec'over 19 is also provided with a spring-pressed" pl-unger 69 which is normally adapted to be received under the catch 58to' retain the door'inclosed'position. The r ar portion of the e'irtensi'on'j58 is, however, beveled asat 7 0, whereby uponengagement of the receptacle with-the dog 68, the plunger '69wi11-b cammed inwardly by the bevel 70, whereby the door will be released fromthe catch and will drop-by gravity to the-open position shown in Fig. 8. Thus it will be seen thatthe dog 57 performs adouble function in both actuating the sleeve, release mechanism and inopeningthe' door19. 4 F. I Inf theoperationiof the present device it will be seen that'jin 'the positionshown in igs; 1 andjS, the truckmay be-movedito the desired position and the'doofq18opened,

whereby the reteptacle 12may receive refuse material. When the receptacle 12 is'lowered, the lev-'er" 1Ojis moved rearwardly, thus moving forwardly tliesleeve 43 and-engaging the gears 33 and 4:1,"whereby the shaft 25 will be rotated and thecable 16 will'move the receptacle upwardly along the track until such time as the receptacleengages the dog 57 The engagement ofthe "dog as hereinbefore described will operate. to open the 49 of the sleeve 32, thus-releasingthe sleeve and 'permltting it to 'move' to the neutral jdischargedo'or 19 'and to move "the plunger" position; When thecontentsi of the receptacle have been discharged, the lever 40 may be moved forwardly thus movingthe sleeve 43; into operative engagement whereby the shaft 25 willbe rotated in a reverse direction and the receptacle will be returnedto thereceiving position, in which position the catch 58 of the receptacle will operate through the bell crank and linkage system to, ,rais'e 'upwardly the plunger 49 of the sleeve 43,"whereby the sleeve willautomatically returnto its neutral position and the device will be ready for an additional load to the receptacle 12.

It will be understood that the invention is not confined to the specific structure herein presented, and that numerous changes and modifications and the full use of equivalents body and movable with respect thereto, said body including track members for guiding said receptacle, said receptacle including roll ers receivable by said tracks, means for moving said receptacle, said means including cables associated with said tracks, means for moving said cables by the motor of said vehicle, said last-mentioned means including a gear mechanism adjustable to move said 2 cables in either direction, plungers for holding said mechanism in adjusted position, and
